"M" for Mainz and "D" for Descant - this is designed to produce the brilliance of sound and projection needed for today's principal and high horn players.

The model M was the first mouthpiece here at Strachan Brass and it's "a mouthpiece for Alexander players in the USA".  It needed to have that classic American sound while fixing some of the deficiencies on the F side that you get on American mouthpieces on Alexanders.  It makes a rich, middle-of-the-road sound; a capable chameleon to let you and your Alex blend into any American section.

As the instrument gets shorter the tone changes to be less brilliant and more "woofy".  Additionally as we play higher the characteristic sound of the instrument changes and that's where the MD comes in.  It reduces the feel difference between the "alto" side of your horn and the Bb or F sides.

Based on the Model G - the MD provides Alex players with options both for sound color and to add resistance and support in the extreme upper reaches of horn playing.  THe MD works great on Alex doubles for players who spend all day up high and is the best choice for Alex descant or triple players.  It even plays solidly on the low F side.
